Three storey house to the right was built in 1796 and the large two storey Regency wing was added 1837. C17 elements recorded by Brycheiniog to rear.  The earlier house was built by Champion de Crespigny who also owned Ty Mawr and was High Sheriff 1796.  The property was bought from Crespigny by JPW Gwynne Holford who erected the later wing reputedly for use as a Dower House.  In order to marry the two separate buildings together the left wing of the 1796 house was itself converted into two floors to create a more seamless join.  Behind the 1796 house evidence has been found of an earlier C17 building.

The interior largely retains the plan established in the remodelling of 1837 and many of its late C18 and early C19 fittings including shutters, panelled reveals and soffit, 6-panelled doors and contemporary glass in the sashes.  The house is Grade II listed due to its architectural merit and its association with estate owning families.

The Gwynne Holford family also owned Buckland Estate nearby at Talybont.  Owner at time of Cathedine Tithe 1839 was a Holford and outline of building only is shown, not hatched, which might imply it was still unfinished at time of survey.  JPW Gwynne Holford (1833-1916), presumably the son of the builder of the Regency house, was Deputy Lieutenant for Brecon and MP for Brecknockshire 1870-90.  The entrance alterations were probably carried out under his ownership. The estate sold following his death in 1919.  Holford family also owned Westonbirt in Gloucestershire.
